Expedition 71 is the 71st long-duration expedition to the International Space Station. The expedition began with the departure of Soyuz MS-24 on 6 April 2024[1] with Russian cosmonaut Oleg Kononenko continuing his ISS command from Expedition 70.[2][3] It will end with his departure on Soyuz MS-25 with crewmates from MS-24 and MS-25 on 24 September 2024.[4][5]
Background, Crew, and Events
[edit]Initially, the expedition consisted of Kononenko, his Russian Soyuz MS-24 crewmate Nikolai Chub (both on a year long ISS mission since 15 September 2023), and his American Soyuz MS-25 crewmate, Tracy Caldwell-Dyson, who launched on 23 March 2024, as well as SpaceX Crew-8 crewmates, American astronauts Matthew Dominick, Michael Barratt, and Jeanette Epps, and Russian cosmonaut Alexander Grebenkin, who launched on 4 March 2024 and were transferred from Expedition 70 after Soyuz MS-24 departure.[5][3][6]
NASA astronauts Barry Wilmore and Sunita Williams arrived at the station on 6 June 2024 as part of the Boeing Crew Flight Test. Their visit was planned to be brief.[4][7][8] However, due to technical issues with their spacecraft, their stay was extended, and they became de facto members of the ISS crew. They assisted with various tasks, including research, housekeeping, and maintenance.[9] On 24 August 2024, NASA announced that the Boeing Starliner spacecraft would return to Earth unmanned with Wilmore and Williams returning on the SpaceX Crew-9 mission in early 2025. NASA also announced that Wilmore and Williams would formally be added to the Expedition 71/72 crew.[10]

Besides the expedition crew, a Boeing Starliner spacecraft is visiting the station for a crewed flight test, consisting of NASA astronauts Barry Wilmore and Sunita Williams.[8] The spacecraft Calypso[13] launched and docked to the station in June 2024. The flight marked the first crewed test flight of the Starliner. Crew members were scheduled to stay aboard the station for approximately 6 days, but the mission was extended due to issues with the spacecraft. Despite months of testing, NASA felt it was not able to understand why the thrusters malfunctioned and decided that it was too risky to return Wilmore and Williams to Earth aboard Starliner. Instead, they will ride down on the SpaceX Crew-9 Dragon capsule, and the Boeing spacecraft will attempt to return uncrewed. It was the first launch of humans from Cape Canaveral since Apollo 7 in October 1968 and first launch of humans from SLC-41.[8] |
